Bottle schools are schools built using plastic bottles stuffed with inorganic trash, known as "eco-bricks". It takes around 6,500 eco-bricks to build a two-classroom school.To make eco-bricks, community members collect plastic soda bottles and stuff them full of inorganic trash such as plastic bags, chip packets and polystyrene, until the bottles are hard like bricks.Bottle schools are an efficient and environmentally-conscious way to help fill the need for educational infrastructure that exists in many countries. Reusing plastic waste to build bottle schools cleans the community of trash, and in the process educates youth about the environmental impact of non-biodegradable waste.Above all, bottle schools are a community effort. It would be very difficult for one person to collect 6,500 bottles and over two tons of trash to build a school. A community, working together, can achieve this.
